SHA1 base64 algorithm in javascript and C#
c#, javascript, sha1
Solution
Would depend on the receiver but try decoding your result from the javascript with C# and you'll get an exception. The = sign is there to pad the result to the correct length.

Problem
I'm running some tests comparing the sha1 algorithm implemented in javascript - got from http://pajhome.org.uk/crypt/ - with its implementation in C#. Using C# to get the hash for {'method':'people.get'} I'm using this statement: ``` Convert.ToBase64String(new System.Security.Cryptography.SHA1CryptoServiceProvider().ComputeHash(Encoding.ASCII.GetBytes("{'method':'people.get'}"))); ``` which gives me `Qy95a0ShZqhbNdt6IF8qNf72jX0=` In javascript I get almost the same: `Qy95a0ShZqhbNdt6IF8qNf72jX0` using the statement: ``` b64_sha1("{'method':'people.get'}"); ``` In the javascript case, the hash doesn't end with a equal (=) sign. Can this difference cause me troubles in authenticating against a server? In my case, as many of you may know, the sentence I'm reckoning the hash goes inside the http body and the server will check it. Thanks
